Sunsynk 20kW HV Commercial 3‑Phase Hybrid Inverter Key benefits 20kW three‑phase high‑voltage hybrid inverter for commercial and light industrial solar‑plus‑storage systems, combining PV and battery control in one unit. High‑efficiency design with up to 97.6% max efficiency and >99% MPPT efficiency to maximise yield from rooftop or ground‑mount PV arrays. Wide 160–800V battery voltage range and up to 50A + 50A charge/discharge current, ready for high‑voltage Li‑ion storage banks. Brief description The Sunsynk 20kW HV Commercial 3‑Phase Hybrid Inverter is part of the Sunsynk three‑phase HI range, designed for medium‑sized commercial and industrial sites that want to combine solar generation with high‑voltage battery storage. With multiple MPPT trackers, high DC input power and integrated protection, it is suited to offices, warehouses, logistics depots and small production facilities needing reliable three‑phase power support. Wall‑mounted IP65 construction and intelligent air cooling allow installation in plant rooms and service areas with minimal maintenance. Key features High‑voltage Li‑ion battery support from 160 to 800V with dual battery inputs and automatic BMS communication. Up to three or four MPPTs (model dependent) with wide 150–850V MPPT range and high DC input power for complex commercial arrays. Three‑phase AC output at 220/380 or 230/400Vac, with low THD and adjustable power factor from 0.8 leading to 0.8 lagging. Integrated protections including DC and AC surge protection, anti‑islanding, residual current monitoring and over‑current/short‑circuit protection. IP65 metal enclosure, intelligent air cooling and operating temperature from ‑40°C to +60°C (derating above 45°C) for demanding commercial environments.
